CHARLES SOHAELLING, OF EUREKA, UTAH.

ELEVATOR ATTACHMENT.

N 0. 837,888. Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed November 25,1905. Serial No. 289,092.

To aZZ whom it may concern: I which, in conjunction with abattery 12, con- Be it known that 1, CHARLES SCHAELLING, l stitutes a normally open electric circuit, ina citizen of the United States, residing at eluding a signaling-bell 13, situated at the Eureka, in the county of Juab and State of engineers station at the top of the shaft, Utah, have invented new and useful Imthere being carried by the car 3 a pair of provements in Elevator Attachments, of l electrically-connected contact-pieces 14,

which the following is a specification. designed to contact, respectively, with the This invention relates to signals for use in wires 11 and complete the circuit through connection with mine-elevators, and has for the latter, while pivoted to a portion 15 of its objects to produce a comparatively simthe framework of theshaft at a point above ple device of this character which may be inl and suitably remote from the chairs 5 is a eXpensively installed for use, one whereby rocking member or lever 16, having its outer due warning will be given of the fact in the 1 end connected by a rod or element 17 with movements of the chairs automatically conevent of the car-receiving chairs being dis- 1 posed within the shaft, and one wherein the trols the setting of the signal.

With these and other objects in view the invention comprises the novel features of l construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a side elevation of an elevator equipped with a signal embodying the invention. Fig. 2 is l a vertical longitudinal section taken on the line 2 2 of Fig. 1. Fig. 3 is a detail perspecj tive view of a portion of one of the chairs and 1 showing the connection between the same and the signal-setting lever. Fig. 4 is a de-' tail perspective view of the cage and showing the signal-circuit.

Referring to the drawings, 1 designates an elevator-shaft including vertical guides 2, between which there is arranged for travel a car or cage 3, there being journaled inthe framework of the shaft 1 and at opposite sides thereof rock-shafts .4, equipped with chair-arms 5 and connected for simultaneous movement by means of pairs of links 6, fixed, respectively, upon the ends of the shafts 4. and having their meeting ends pivotally connected, as at 7. The chairs are adapted for i l l l l the links 6 at their pivotal point 7 and pro vided at its inner end with an insulated contact-piece 18, adapted to bridge the wires 11 and to bear upon both of said wires for moving them to contacting position, as hereinafter explained. The lever 16 is acted upon and maintained in normal position by a leafspring 19, fixed at one end to the framework of shaft 1.

In practice the shaft 1 will be equipped with a plurality of sets of chairs 5, disposed, respectively, at the different levels in the shaft, it being understood that when the car is to be brought to rest at any determined level the lever 8 will be operated for rocking the shafts 1 and projecting the chair-arms 5 into the shaft within the path of the car, which will when stopped rest upon said arms. As the shafts 4 are rocked for swing' ing the arms inward the pivotal point 7 of the links will move downward, thus serving, through the medium of the rod 17, to rock the lever 16 on its pivot, whereupon the wires 11 will be forced outward in the shaft by means of the insulated piece 18. and within the path of, the contact-pieces 14, whereby as the car descends, the pieces 14 in contact ing with the wires 11 will complete the circult and ring the bell 13, thus warning the operation by means of a lever 8, connected l engineer of the fact that the car is approachwith one of the shafts 4 by means of a link 9 l ing the chairs 5 and in order that the car for moving the arms 5 into and out of posimay be brought to a proper stop. It is to be tion within the shaft 1, there being provided understood in this connection that the set a rack 10, adapted for engagement by a suit- 1 ting-lever 16 is disposed a suflicient distance able pawl on the lever to 11X the latter against above the point of location of the chair-arms movement for maintaining the chair in adl to give ample time within which to check the justed positions. The foregoing parts may speed of the car before reaching said arms all be of the usual or any appropriate conand, furthermore, that whenever the chairs struction and material and are adapted in l are positioned to contact with the car the practice to perform their usual functions. lever 16 will be set for moving the wires to Extended downward through the shaft 1 position for contact with the pieces 14, and connected at their lower ends with one while, on the other hand, when the chairs ocof the frame-beams is a pair of wires 11, l cupy the position illustrated in Fig.1 and out of the path of the ear the wires will be maintained in position for non-contact with the pieces 14. Thus it will be seen that in the event of the attendant failing to move the,

chairs 5 to non-dan er position or, that is, out of the-path of tie car the parts of the mechanism will be set, and as the car descends the shaft the alarm will be sounded at the engineers station, thus to permit oi the car being stopped before reaching the chairs, and consequently obviating liability of an accident.

Having thus described my invention, what I claim is Y 1. In a device of the class described and in combination with an elevator-shaft, a car 5 movable therein, chair members adapted for movement to a position within the shaft for 3 contact member, and means controlled by the movements of the chair members for operating the rocking member to move the wires to contacting position.

2. In a device of the class described and in combination with an elevator-shaft, a car arranged for movement therein, electricallyconnected contact-pieces carried by the car, a circuit including a signal and comprising wires extended into the shaft, chair members adapted for movement into the shaft to receive the car, links connecting the chair members, a rocking member having an insulated bar adapted to engage and press the wires into the path of the contact-pieces, and connections between the links for operating the former to move the wires to contacting position.

In testimony whereof I allix my signature in presence of two witnesses.
